Personally, I liked the Demonata series.
And, with the exception of Loren(that green guy who reads your thoughts when you sing) off of that Angel spin-off of Buffy, I've yet to find a... favorable? Depiction of a demon in Western media.
I go for books for the plot line, not whether they depict anything remotely resembling me. And I'm not offended when someone says "hey, demons are bad," because hey, my usage of the term "demon" is not as widespread as the dark, doomy usage.
So no big deal. It's comparable to a therian getting offended by werewolves in movies.
